LYCOMING AIRCRAFT ENGINE GROUP ASSEMBLY PARTS LIST

INTRODUCTION

This catalog contains a complete parts listing for GSO-480 and IGSO-480 Series aircraft engines. The followingengines are contained herein: GSO-480-A1A6,-A2A6,- B1A6, - B1B6,- B1C6, - B1E6,- B1J6, - B2D6. IGSO-480- AA6,-A1B6, -A1C6, -A1E6, -A1F6.

The catalog is laid out to present major sub-assemblies in a chronological order. Sub-assemblies are notnecessarily listed in engine build up order, but will follow this order wherever possible.

The illustrations contained herein will endeavor to place a specific part in its exact location in a particularsub-assembly. Whereto doso would confuse correct position of the part, dottedlines willbe usedto assure correctlocation. No more parts will be shown in any illustration than appear on a single page. Where comparatively fewparts are shown, an illustration will depict those parts in the listing directly above the illustration. There maybe more than one illustration to a page under these circumstances.

All engine model identifications are listed as the engine left the factory. Individual engine modifiers are re-sponsible for ordering the correct parts for any modification performed after the engine has left the factory. Ex-cepting, of course, those modifications performed to conform with existing Lycoming Service Bulletinsand/or Instructions.

The following instructions are issued as a guide to the correct use of this catalog.

1. If youknow the name of the part, turnto the Table of Contents. Parts are listedhere by major sub-assembly,and component parts.

a. If you do not know name of the part, check the sub-assembly, in which you think the part may be located.

2. The Table of Contents will point out both a section and a particular page for part in question; i. e. ConnectingRod and Bearing, Section IV, page 4-2.

3. Turn to chart that precedes Section IV. Under the column marked "Engine Model" find model engine yourequire.

4. Moving to the right you will encounter several individual column headings identified by component parts andpage number; ie. Connecting Rod and Bearing, page 4-2.

5. Moving from the top of this column down, select the letter code (A, B, etc. ) that is directly opposite themodel engine you are interested in.

6. Turn to page 4-2. Under "Description" column, you will find the part in question listed by its proper name.Preceding the description the part is also identified by Part Number and a Reference number. The Referencenumber refers to location of part in accompanying illustration.

7. In Model usage column you will find a letter code (A, B, etc.).

8. Select the same letter that was indicated in Step 5. Since only the letter "A" is shown, all models in thiscatalog use the same Connecting Rod.

A typical example: Find the correct exhaust valve for IGSO-480-A1E6 model engine.

(1) Turn to Table of Contents in front of catalog. Note that valves and springs are in Section IV, page 4-5.

(2) Turn to Section IV. Using the chart at the beginning of this section, find engine model IGSO-480-A1E6.

(3) Move to right to individual column heading, Valve and Springs. This is on page 4-5. Note that letter codeopposite IGSO-480-A1E6 is "B".

(4) Turn to page 4-5. The letter"B" is opposite the 74802, 1/2 in. stem diameter inconel exhaust valve andalso the 73111 1/2 in. stem diameter standard exhaust valve. This signifies that either valve may be usedin IGSO-480-A1E6 model engines.

9. A much faster procedure, if the part number is known, would be to find part number in numerical partsnumber section. This section lists all parts in numerical order. It also identifies; the Description, Page No.Ref. No. and Quantity used.

10. If neither part name or part number is known, check the illustrations. Since the illustrations now containfewer parts, it is easier to isolate a part, by sight.

VENDOR ACCESSORIES

SECTION IX

This section has been compiled to enable field personnel to more

efficiently arrive at adequate parts coverage for vendor supplied

accessories.

An asterisk (*) has been used to point out those parts stocked by

Lycoming. Note that only Lycoming stocked parts have been called

out on the illustrations. The exception to this will be found on the ex-

ploded views of Bendix Scintilla magnetos. Since Lycoming does

stock most of the magneto parts, all parts have been listed.

Most vendor accessory parts lists are available from Service Depart-

ment, Lycoming Division, Williamsport, Pa. 17701.
